This may be a bug or a subtle API difference because the clamped and not clamped to ground polygons use different primitives under the hood.

Can you post a Sandcastle example (https://sandcastle.cesium.com/index.html?) of how you’re creating this polygon? You can click “share” in the top and paste the link you get here.

this is my example on Sandcastle. if you do not set height for polygon, black background will disappear

Thanks for reporting this. This is definitely a bug. I proposed a potential fix here: https://github.com/AnalyticalGraphicsInc/cesium/pull/8349
